How has your approach to gear changed in 2020?
Since the pandemic hit—like a lot of people—I've been playing solo a lot more. I don't know if I'd chalk it up more to boredom or a real need but I found myself looking for a different sound.
So after 10+ years playing heavy La Bella flats on my P-bass, I switched back to roundwound strings this year. It's been a lot of fun for solo improvisation and the amateur recording I do at home. (I even switched to Spirocores on my upright after many years with Evah Pirazzi, which was a similar experience... but that's a topic for another thread.)
I also rarely use my amp anymore.
What about you?
I used to gig nearly every weekend, but that ended back in March. Most gigs were cancelled, but I had a number of summer offers come in that I declined out of concern about COVID. I wound up accepting two of those offers -- various reasons. I wasn't thrilled about exposing myself to risk, but was TRULY thrilled to fire up my gig rig again!

I can't do that at home because I live in a condo (though I do like my Fender Rumble 1x10 combo a lot).
What I'm trying to do is replace lost gigs with lengthy home rehearsal sessions: I do NOT want to lose my endurance by the time the gigs return. I've decided to challenge my fingers by playing songs by Rush, Pat Travers, Red Hot Chili Peppers -- best I can do, as I've never had JacoChops(tm). Scheduling these lengthy rehearsals can be a challenge. Used to be easy to keep my fingers in shape for three one-hour sets: I'd go to the gig! Here at home, lengthy sessions are harder to schedule and there can be interruptions.
Oh wait... you're asking about gear! Actually, the biggest factor for 2020 isn't COVID, it's the fact that I've been too extravagant over the past 5+ years. I now have all the gear I need plus more. I'm happy, and can truly say that I have no significant GAS. I had already planned on a frugal gear year, and the pandemic has made it easy for me to stick to that plan. Instead of buying new stuff, I've been enjoying all the gear that I own (aside from my gig rigs, unfortunately). I've been rotating through all my basses (10), and all of my overdrive pedals (a dozen-plus). I love variety: all my basses sound different, same with the overdrives.
All that said, I've made three relatively minor gear purchases here in 2020:
* Darkglass Harmonic Booster 2 EQ pedal: because semi-para mid is cool, and none of my amps have it
* HPF Tech (fdeck) HPF3 pedal: because I did not own an HPF
* Tronographic Rusty Box: was on my wish list forever, couldn't say no to the limited edition Halloween run. Unlike the previous two it doesn't fill a void in my gear collection, but it sounds great and I'm glad I got it. Essentially I consider it a COVID consolation prize.
